To all whom it may concern.-

Be it known that I, ISAAC E. PALMER, of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvement in Fringe-Making Attachments for Hammock-Looms, of which the following is a specification.

My invention relates to an improvement in fringe making attachments for hammocklooms, with the objects in View of providing a mechanism to be carried by the lay-beam of the loom in position to weave a fringeinto the edge of the hammock simultaneously with the weaving of the hammock-body, the weaving of the warp and weft threads of the hammock-body serving to secure the fringe in position.

A further object is to provide a mechanism in which the weaving of the fringe may be so timed relative to the weaving of the hammock as to make the fringe considerably thicker than the weft of the hammock, the said fringe, if so desired, being of a distinguishing color from the weft-threads of the hammock, the said fringe being formed by the weaving of a single thread into the edge of the hammock-body. by looping the same and severing the loops at their outer ends.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents a vertical section through a portion of a hammock-loom from front to rear, the fringe-making attachment being shown applied thereto. Fig. 2 is a front view of a portion of the loom and hammock-fringe attachment. Fig. 3 is an enlarged front view of the fringe-formin g mechanism proper, the several parts being shown in the positions which they assume as the outer end of the loop of the fringe is being severed. Fig. dis a similar View, the parts being shown in the position which they. assume when the hooks are about to engage the thread which forms the fringe, to draw it out to form the loop. Fig. 5 is a top plan viewof the loop-forming mechanisni,the parts being shown in the same positions as in Fig. 8. Figs. 6 and 7 represent a front viewof the upper portions of thefringe-forming mechanism with certain portions broken away to more clearly show the operation oftne springactuated swinging cam, the parts being shown in two positions intermediate of those shown in Figs. 3 and 4E; and Fig. 8 is an exaggerated view of a portion of the hammock-body and fringe, showing the manner in which the fringe is secured along the edge of the hammock-body.

In the accompanying drawings I have only shown so much of a hammock-loom as is necessary to illustrate the practical operation ofmy improved fringe-making attachment.

The lay-beam is denoted by A, and it is given its usual forward and back-swinging movement by the crankshaft B through a suitable connection 0.

The main drive-shaft is denoted by D, and it is provided with a suitable cam cl in position to engage a tappet E for controlling the up-and-down movement of the heddles F.

The fringe making attachment is constructed. as follows: A suitable supporting-plate G is provided, which supporting-plate is adapted to be secured to the lay-beam A, so as to rock therewith. The said supporting-plate G is shown in the accompanying drawings as being secured to the lay-beam A by means of suitable screws g g.

A stub-axle H is secured to the plate G and projects forward therefrom. The stub-axle H is preferably removably secured to the plate G. This result is obtained in the present instance byscrew-threading the end of the axle, which projects through the plate G, as shown at h, and providing a clamp-nut h.

A rocking plate I is mounted upon the stubaXleH, so as to rock in a plane at right angles to the rocking movement of the lay-beam A. The rocking movement of the plate I is controlled by the following mechanism:

A retracting-spring J is connected to the rocking plate I, tending to rock it to the limit of its inward movement relative to the hammock-body. The plate I is rocked to the limit of its outward movement against the tension or the spring J by means under the control of the main drive-shaft D. The particular means which I have shown in the' accompanying drawings for positively rocking the said plate outwardly are a cam cZf, fixed to rotate with the shaft D, a two-armed lever K,the upper arm of which is located in positionto be engaged by the cam (Z' and its other arm 7); hav ing a flexible connection L with the plate I, so that as the arm 7t" is rocked downwardlyit will rock the plate I outwardly.

The rocking plate I is provided with a suitable spring-actuated swinging cam M, pivoted at one end to a suitable ear or lug i on the plate I, its spring on tending to keep the free end of the swinging cam M down into engagement with the periphery of the plate.

The needle through which the trio ge-thread passes is denoted by N, its spring-actuated swinging needle bar by n, which bar is pivoted at its inner end, as shown at n, to an uprising ear or lug g upon the supporting-plate G. The swinging needle-bar n is provided with a laterally-exten ded projection 71 which projection is adapted to travel around the spring-actuated swinging cam M as the plate I is reciprocated for the purpose of bringing the needle N with its thread first up into the path of the warp and weft threads of the hammock-body and then allowing it to drop down out of the way of said warp and weft threads at proper intervals.

The rocking plate I also carries a pair of hooks O 0 and a guard I. In the present instance the guard is shown as secured to the plate I, as at p, and the pair of hooks O 0 are secured, as shown at o, to the guard P, the said hooks being spaced a sufficient distance apartto enable them to pass freely upon .opposite sides of the cutting-blade, to be hereinafter described, as the rocking plate I is recip rocated. The hooks are located in position to engage the fringe-thread upon one side of the needle and draw the said thread outwardly as the plate I is rocked in one direc-.

tion to form the loops of the fringe. A suitable cutting-blade Q is secured, as shown at q, to the supporting-plate G, with its cutting edge q in position to enter the space between the ends of the hooks O 0 when the hooks are rocked outwardly for the purpose of severing the outer end of the loop to form the fringe.

The operation of my invention is as follows: Suppose the parts to be in the position shown in Fig. 3, with the cutting-blade just severing the outerend of a loop. The rocking plate I in this view is shown as being rocked to the limit of its outward movement by the engagement of the cam d with the rocking lever K. As the cam 61 releases its engagement with the lever K the retractingspring .I will swing or rock the plate I inwardly. As the plate I is swung inwardly the free end of the needle-bar n will ride up along the top ofthe spring-actuated swinging cam M, thereby raising the needle with its thread up into position to cause the said thread to be woven into the selvage or edge of the hammock-body. At the same time the hooks O 0 are being caused to rock rearwardly to a point beyond the needle, the guard I serving to prevent the said hooks from catching in the hammoclcbody. The latter part of the inner swinging movement rock outwardly.

-wardly the free end of the swinging needleof the plate I will cause the free end of the needle-bar to drop down onto the periphery of the rocking plate, thereby withdrawing the needle from the hammock fabric and at the same time drawing the fringe-thread down into position to be engaged by the hooks O 0. The engagement of the cam d with the rocking lever K will then cause the plate I to As the plate is rocked outbar a will travel along the periphery of the plate I between it and the inner wall of the spring-actuated swinging cam M, the free end of the said cam being caused by the lateral projection 01 upon the needle-bar to allow the needle-bar to escape between the free end of the swinging cam and the plate bringing the said swinging arm into position to again ride up the top of the cam when the plate is rocked inwardly. As the plate is rocked outwardly the needles carry the thread along with them, and after it has been drawn out to the proper length the cutting-blad e'or knife Q engages the thread between the hooks and severs it, thereby forming the fringe.

The knife maybe so adjusted as to cut the thread at the proper time and the rocking movement of the plate I may be so arranged as to form any depth of fringe which may be desired. Furthermore, the said plate may be rocked twice to every backand-forth movement of the weft-thread, so as to form a fringe twice as thick as the weft of the hammock, if so desired.

The parts of the fringe attachments are so timed relative to the weaving of the ham-. mock-body that the needle will be caused to swing upwardly into the path of the warp and weft threads which are being woven to form the hammock-body at the proper time to secure the thread which is to form the fringe before the hooks are caused to engage the thread to pull it outwardly to form the loop, so that when the knife or cutting-blade Q severs the outer end of the loops the rear end of the loop is securely fastened into the edge or selvage of the hammock-body, so that the said hooks are free to swing back into position to again engage a new portion of the fringe-thread to draw out another loop.

It is evident that slight changes might be made in the structure and arrangement of the several parts without departing from the scope of my invention. Hence I do not wish to limit myself strictly to the structures here in set forth; but

What I claim is l. The combination with means for weaving a strip of fabric, of means for in trodncing a separate thread into the edge of the strip as it is being woven and means for looping the separate thread in the body of the fabric at a distance from the edge of the fabric independently of the weft-threads of the fabric, substantially as set forth.
